I have been agonising for quite sometime on a 6/8" scope and have finally come down to two choices.
1. 6:" f12 Achro as an ATM.
2. 6" f8 R35 as a replacment objective in my Synta tube, should it become reality, fingers crossed as I think this would sell like mad.
My final ( yeah sure) thing to work out, and I'm sure I know the answer but need reassurance, is the f8 R35 will be capable of a wider field of view than the f12, correct?
If I can use my NEQ6 with whatever I end up with I'll be very happy....so will my wife.

When I tested a 150-8 R35 a couple weeks ago the full moon fit in the field with room to spare using a 25mm plossl. Man was that a beautiful sight. I never get tired of it. Both lenses will perform well but the F8 R35 is a superior design and uses low dispersion glass (not ED). It's a little heavier than the standard achros but the R35 is a "slim" design. I guess the question becomes do you put money into an older scope. Is it in good shape? Do you like the focuser? Is your mount adequate to carry a scope the length of an F12? Weight is usually not so much the issue as laying flat on your back to see the zenith. The F12 will deliver less CA. But looking through the F8 at the moon it was evident the color correction was better than any standard F8 achro. I need to get Jupiter in the eyepiece to really determine the amount of CA. It's coming soon.
